I'd have to say I enjoy myself a lot more, really. I don't feel so much responsibility as I did in other teams. It felt sometimes at Ajax and Liverpool that it had to be me. Now, every time I go out on to the pitch, I enjoy myself and laugh. I have gone through too many difficult times in my career and I don't want to keep thinking about them.

I worry when I can’t help the team with everything I have to offer.

I lost my balance, making my body unstable and falling on top of my opponent. At that moment I hit my face against the player leaving a small bruise on my cheek and a strong pain in my teeth.

At first I didn't think I was going to fit into Barcelona's way of playing. There was a lot of tiki-taka and I was thinking that without a lot of space to play in, I'd find it more difficult. I worried about that.

Look, there’s no rule in soccer against biting your opponent. There’s not even a rule against eating your opponent. The only rule in soccer is that you can’t use your hands.

I swear on my children's lives that I never look at the statistics or look at beating anyone's records. All I do is look to improve but not compete against any record. I want to win trophies and score goals because that's my job as a forward.

My desire at Liverpool was to help get the club playing in the elite because they had been five years without it. We used to talk about it in the dressing room. If Liverpool are not in the Champions League, it is difficult to get the best players to come to the club.
